Directions: Combine the peaches, blackberries and sugar in a large bowl. Let stand for 15 minutes. In a separate bowl, stir together the flour , oats, sugar, milk, vanilla, and melted butter to form a thick batter. Spray an 8x8x2 baking pan with non-stick spray. Spread the batter into the bottom of the pan. Spoon the fruit mixture on top. Bake at 400 degrees for 45 minutes, until the bottom of the crust is golden and puffing over. Serve warm with ice cream.
